Model Available: LH 15/12 - LF 120/14

The LH 15/12 - LF 120/14 laboratory furnaces have been trusted for many years as professional chamber furnaces for the laboratory. These furnaces are available with either a robust insulation of light refractory bricks (LH models) or with a combination insulation of refractory bricks in the corners and low heat storage, quickly cooling fibre material (LF models). With a wide variety of optional equipment, these models can be optimally adapted to your processes.

Tmax 1200 °C, 1300 °C, or 1400 °C
Five-sided heating for very good temperature uniformity
Heating elements on support tubes ensure free heat radiation and a long service life
Protection of floor heating and flat stacking surface provided by embedded SiC plate in the floor
LH models: multilayered, fibre-free insulation of light refractory bricks and special backup insulation
LF models: high-quality fibre insulation with corner bricks for shorter heating and cooling times
Door with brick-on-brick seal, hand fitted
Short heating times due to high installed power
Side vent with bypass connection for exhaust pipe
Self-supporting arch for high stability and greatest possible protection against dust
